Plastic-steel-composited bearing trench cover plate

Abstract

The invention relates to a plastic-steel-composited bearing trench cover plate which comprises a bearing framework, a filling layer is injected in a cavity of the bearing framework, and an elastomer surface layer is wrapped and pasted on the outer surface of the bearing framework in an omnibearing manner. The tabular load-bearing framework is made of a steel material, plastic or foamed cement is injected in the cavity of the framework to form a cover plate supporting body foundation, and the cover plate supporting body foundation is wrapped by the elastomer surface layer in a mold-pressing manner to complete manufacturing of the cover plate. The plastic-steel-composited bearing trench cover plate has the advantages of high bearing capacity, easiness in molding, firmness in wrapping and adhering, graceful appearance, resistant to corrosion and the like, and a surface-layer colored plastic veneer can be replaced according to needs to beautify the environment.

Description

technical field [0001] The invention relates to a ditch cover, in particular to a plastic-steel composite load-bearing ditch cover made of cement, section steel and plastic materials. Background technique [0002] Trench cover is also called trench cover or gutter cover. In real life, this type of cover is mainly used in the following aspects: [0003] 1. Factory workshops, restaurant kitchens, bath centers, and large buildings. In order to make the terminal layout of water, electricity, gas, fire protection and other facilities more reasonable and convenient. There are more or less open trenches for pipeline laying and installation of upper and lower waterways. After installation, these trenches will be sealed with cover plates. [0004] 2. In the intersection of various pipelines in urban blocks, in order to facilitate the crossing of pipelines and maintenance, some open trenches will be left to be sealed with such covers. [0005] 3. In urban parks, green spaces, and ...
